Well no, PR Electronics is currently releasing a new system of barriers with IECEX approvals and SIL2 for most models. These are programmable with a clip on display with push buttons to reduce the number of types required to cover all normal industrial applications.

The PR 9000 series modules can be used as stand alone, DIN rail mounts, or clip onto the PR9000 Power Rail system. Power distribution to the rail, supply redundancy, and centralization of a common module alarm system is managed with the PR-9410 Power Control Unit.

The 9000 series is very highly positioned in terms of performance and reliability, with better than 0.1% accuracy and 5 years warranty and SIL 2 on most models. SIL 2 Certification is by Full Assessment, and PR Electronics is the first in the world to have this type of approval.

Modules are programmed using the PR 4501 clip on display /programmer. Menu systems used for module set up are simple to use and the menus are intelligent in structure [adapt as the configuration proceeds] and there is a single path, so no parameters are missed in a programming session.

An example of a newly released module is PR 9116.

This has input for RTD, Resistance, Thermocouple, Potientiometer, and mA, with transmitter power supply, and a relay output with selectable function. Required supply voltage is 19.2-31.2 VDC and isolation is 2600VAC. Programming is password protected, each module can be allocated, and will display on the PR-4501, a custom TAG number.

More than 2 /3 of the modules have been released for sale in Australia, and the remaining [being the HART transparent modules] are due for release in the next few months. PR Electronics has been producing ATEX certified barriers for many years, so they have a huge body of experience. The extreme rigour, of the approvals for SIL2, and IECEX has assured that this product is the best available from any supplier.
